How to print with Ultimaker PP

PP (polypropylene) is a commonly used polymer in the industry. Properties of Ultimaker PP include exceptional layer bonding and good adhesion to the build plate, especially when using adhesion sheets.

Note: The information provided here applies to Ultimaker PP, similar quality cannot be guaranteed with third-party filaments.

Compatibility

Ultimaker can be printed on the Ultimaker S5, Ultimaker 3, and Ultimaker 2+, but is not compatible with all nozzle sizes. We don’t officially support printing PP with a 0.25 print core / nozzle. If you use this material on the Ultimaker S5 or Ultimaker 3, make sure to use an AA print core.

Note: Ultimaker PP is not supported on the Ultimaker 2 Go, Ultimaker 2 (Extended), Ultimaker Original+, and Ultimaker Original

PP doesn’t adhere well to other materials, and therefore it is only officially supported for single-extrusion prints. Experimental use of PP with both extruders on the Ultimaker S5 or Ultimaker 3 can be done.

Recommended settings and configuration

Note: Always use the latest version of Ultimaker Cura and make sure that your 3D printer is updated with the latest firmware version to include the correct material profile for Ultimaker PP.

Temperatures

Ultimaker PP prints at a temperature between 205 and 220 °C for profiles. The build plate temperature is either set to 85 or 100 °C, depending on the selected configuration and profile.

Note: The correct temperatures are automatically used based on the printer, nozzle size, and profile you select in Ultimaker Cura.

Adhesion

Ultimaker PP is prone to warping. Therefore, the use of the adhesion sheets (available separately or in the Advanced 3D Printing Kit for the Ultimaker 2+ or Ultimaker 3) is strongly recommended when printing with Ultimaker PP. This ensures optimal adhesion to the build plate. Please note that using glue as an alternative adhesion method will be insufficient for reliable adhesion of large prints.

Adhesion sheet applied to the build plate

All default profiles for PP in Ultimaker Cura use a large brim (20 - 25 mm) as a build plate adhesion type. A brim is made of several extra printed lines around the initial layers of the 3D print to ensure successful adhesion to the build plate and to avoid warping. Please note that this brim will reduce the printing area of your build plate.

Once your 3D print has finished, wait for cooldown before removing it from the build plate.

Print environment

To prevent warping, we also recommend using the front enclosure included in the Advanced 3D Printing Kit (for the Ultimaker 2+ or Ultimaker 3). This will keep the temperature inside the 3D printer at around 45 °C and provides a higher print success rate, better quality, and better performance of the printed parts. On the Ultimaker S5 glass doors are integrated with the printer, so additional accessories are not necessary.

Health and safety

Ultimaker PP is safe to print when using the recommended temperature settings listed above. To ensure a comfortable and healthy working environment, we recommend 3D printing in a well-ventilated area.
